28. 9 Transducer Installation DTTS DTTC Small Pipe Transducer Installation The small pipe transducers are designed for specific pipe outside diameters Do not attempt to mount a DTTS DTTC transducer onto a pipe that is either too large or too small for the transducer Instead contact the manufacturer to arrange for areplacement transducer that is the correct size 1 Apply a thin coating of acoustic coupling grease to both halves of the transducer housing where the housing will contact the pipe See Figure 14 2 On horizontal pipes mount the transducer in an orientation so the cable exits at 45 degrees from the side of the pipe Do not mount with the cable exiting on either the top or bottom of the pipe On vertical pipes the orientation does not matter 3 Tighten the wing nuts or U bolts so the acoustic coupling grease begins to flow out from the edges of the transducer or from the gap between the transducer halves IMPORTANT Do not overtighten Overtightening will not improve performance and may damage the transducer 4 If signal strength is less than five remount the transducer at another location on the piping system MW 1 16 in 1 5 mm Acoustic Couplant Grease Figure 14 Application of acoustic couplant DTTS DTTC transducers NOTE If aDTTS DTTC small pipe transducer was purchased separately from the transmitter the following configuration procedure is required Page 20 TTM UM 00369 EN 02 April 2015 Transduc
